Custom shortcuts for selecting brushes?
By default, pressing C in Sculpt Mode will select the Clay brush.

Similarly, pressing ShiftC will select the Crease brush.

You can simply change either of these shortcuts to the Clay Strips brush instead. Or you could add a new shortcut of your own using the same syntax.

In the screen shot below, notice how I've changed the function of the second shortcut to trigger the Clay Strips brush instead of the Crease brush.



Let's say you want to add your own instead of modifying the existing shortcuts. It's as easy as clicking "Add New", pasting in paint.brush_select, setting the Paint Mode to Sculpt, then selecting which Sculpt Tool you want. And of course specify the key, and the modifier key(s) if any.
